Last but not least, I would like to thank each and every member for their support and encouragement.

Our solo sponsor Pete Sergeant has been a great support to keep us motivated. We are lucky that he agreed to continue the journey with us in the year 2021. I would like to personally thank Pete and his entire team for their generosity. It would be great if we could add few more to sponsor the prize money so that we could go back and declare weekly champions as we have done in the past. I hope and wish this will become possible in 2021. The amount doesn’t have to be huge. However, it would be nice to show off bunch of supporters. If an organisation comes forward and supports us then that would be the ultimate achievement.

TASK #1 › Represent Integer

Submitted by: Mohammad S Anwar

You are given a positive integer $N and a digit $D.

Write a script to check if $N can be represented as a sum of positive integers having $D at least once. If check passes print 1 otherwise 0.

Example

Input: $N = 25, $D = 7
Output: 0 as there are 2 numbers between 1 and 25 having the digit 7 i.e. 7 and 17. If we add up both we don't get 25.

Input: $N = 24, $D = 7
Output: 1

TASK #2 › Recreate Binary Tree

Submitted by: Mohammad S Anwar

You are given a Binary Tree.

Write a script to replace each node of the tree with the sum of all the remaining nodes.

Example

Input Binary Tree

Output Binary Tree

Last date to submit the solution 23:59 (UK Time) Sunday 23rd May 2021.
